I'm here to share some reasons why you're unable to connect your Venmo account to QuickBooks Online, joe.
Firstly, we need to ensure that the login credentials you entered are correct so that we can log in without any issues. Also, I suggest double-checking the bank's URL to guarantee you're directed to the correct web page.
Moreover, It would be helpful if you could provide screenshots of any error messages encountered during linking. By doing so, it will help us provide a proper resolution to this.
On the other hand, once you've confirmed that everything is correct, we can troubleshoot this issue. Since there are times when your browser's cache will be filled, and will cause issues when working with your QBO account. I recommend opening your account using incognito to help your computer run optimally and regain some storage space to continue working seamlessly.
You can use these keyboard shortcuts to open your private window.
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Safari: Command + Option + P
You can clear your cache since it can help fix certain browser concerns. On top of that, use an updated browser so you can experience the full advantage of the program.
